Onion Tanks/Collar Tanks

"Short Term Portable Storage”

Onion tanks (also referred to as flexi tanks, collar tanks, collar dams or onion bladder tanks) are a self supporting, easily relocatable liquid storage tank made from a variety of fabrics like reinforced PVC. They are distinctive by the central foam filled collar, that will rise as the tank is filled. The unique design of the onion tank means that they have a very quick setup time. Typically 1 or 2 people can have a unit ready to go in about 5 or 10 mins. Onion tanks are the ideal collapsible water tank.

Onion tanks are a perfect solution for temporary liquid or chemical storage and where rapid deployment is required. They are also designed for ongoing use and an onion tank will, when properly maintained offer a long service life.

Fabric Solutions Australia manufactures a range of onion tanks, suitable for a variety of applications containing liquid from 1,000 litres to 30,000 litres. Since no two applications are the same, we use a wide range of materials and allow customisation of all fittings and accessories. We can meet your specific storage requirements, whether you are storing potable water, chemical waste or some other liquid.
